  • Patent number: 9738195
    Abstract: This invention is an Automotive Center Console Armrest Storage Box Lid Protector that is an alternative for replacing the factory installed center console/storage box armrest lid when damaged or to be used to for driving comfort as creates a barrier between the factory installed lid and the under forearm of the driver or passengers forearm. It is designed to be installed over the factory installed lid and is held in place with an elastic band or drawstring sewed on the underside of the fitted fabric piece to keep the fabric protector from slipping. It can be made with or without an added sleeve pocket sewed to the top side as in the sketches. Drivers and passengers that rest their forearm on the center console while driving can have added comfort with this protective cover and also can be used as an alternative to replacing the factory installed hard cover after being damaged from use stains and UV rays. It is installed by opening the lid inserting the protective cover by hand over the factory installed lid.

  • Patent number: 7991571
    Abstract: Pade Approximant function emulators are used to model the nonlinear offset and/or nonlinear sensitivity behaviors of a sensor relative to temperature sub-ranges and to produce temperature compensating corrections for both offset and sensitivity as desired. In order to avoid use of brute force division for generating the Pade Approximant function signals, in one set of embodiments, feedback is used to provide a corresponding effect. In order to minimize the number of coefficients that are to be resolved and stored, in one set of embodiments, first or higher order Pade Approximants with normalized denominators are used so that each function can be defined with just three coefficients. Embodiments that are more analog in nature or more digital in nature are disclosed. Methods for resolving the Pade Approximant coefficients and calibrating each sensor unit on a mass production basis are also disclosed.

  • Publication number: 20080270062
    Abstract: Sensors and/or transducers can exhibit nonlinear response to temperature changes in terms of offset and also in terms of sensitivity to variations in a sensed physical attribute (pressure, strain, displacement, etc.). Padé Approximant function emulators are used to model the nonlinear offset and/or nonlinear sensitivity behaviors of a given sensing means relative to one or more temperature sub-ranges and to produce temperature compensating corrections for both offset and sensitivity as may be desired. In order to avoid use of brute force division for generating the Pade' Approximant function signals, in one set of embodiments, feedback is used to provide a corresponding effect. In order to minimize the number of coefficients that are to be resolved and stored, in one set of embodiments, first or higher order Pade' Approximants with normalized denominators are used so that each function can be defined with just three coefficients.

  • Patent number: 4084274
    Abstract: A turning bed which can be tilted mechanically to turn the occupant from side to side, comprising a tilting assembly pivotally secured to a bed frame of known type. The tilting assembly consists of a mattress frame longitudinally divided into at least three parts: a center section with an outer section(s) pivotally connected adjacent each longitudinal side of the center section. The pivotal connection is such that when the center section is tilted, the outer section(s) adjacent the raised side of the center section is/are tilted as one with the center section, and the outer section(s) adjacent the other side of the center section pivot(s) relative thereto. The center section is pivotally supportable from the bed frame, and can be tilted by a lever secured at one end to the center section, the other end of the lever being moveable (by suitable means such as a screw-and-nut arrangement) to tilt the center section.
